Robust Asynchronous Stochastic Gradient-Push: Asymptotically Optimal and Network-Independent Performance for Strongly Convex Functions
Artin Spiridonoff, Alex Olshevsky, Ioannis Ch. Paschalidis
We consider the standard model of distributed optimization of a sum of functions $F(\bz) = \sum_{i=1}^n f_i(\bz)$, where node in a network holds the function $f_i(\bz)$. We all…
Graph-Theoretic Analysis of Belief System Dynamics under Logic Constraints
Angelia Nedić, Alex Olshevsky, César A. Uribe
Opinion formation cannot be modeled solely as an ideological deduction from a set of principles; rather, repeated social interactions and logic constraints among statements are con…
Deterministic and Randomized Actuator Scheduling With Guaranteed Performance Bounds
Milad Siami, Alex Olshevsky, Ali Jadbabaie
In this paper, we investigate the problem of actuator selection for linear dynamical systems. We develop a framework to design a sparse actuator schedule for a given large-scale li…
Fully Asynchronous Push-Sum With Growing Intercommunication Intervals
Alex Olshevsky, Ioannis Ch. Paschalidis, Artin Spiridonoff
We propose an algorithm for average consensus over a directed graph which is both fully asynchronous and robust to unreliable communications. We show its convergence to the average…
